Hi guys just finishe a job running new pipe from the mains to the kitchen and bathroom hot and cold supplies. Customer has just phoned me and said that the pressure is low. The old pipe was wider than 15mm and i think it was lead. Now it's all 15mm. Is that the problem?


Hoping to get some replies asap lol because I have to go back now.

Did you put new taps in?

Did you put new taps in?

No. I have a feeling i may have repiped wrong somewhere as it was spaghetti junction under the sink. It's a combi and there is hot water coming out the taps. Not sure what I can try to fix it.

Sorry no just out the hot.

As long as you’ve piped it correct and the new pipework & fittings had no foreign objects or muck inside them prior to the install – you should be good.

Partially closed ISOs?!

It could be a coincidence – the combi is playing up!? It's a long shot though.
